The control cabinet is mounted on a base.

[0010] Furthermore, the mounting assembly includes: a rotating sleeve, a round rod, and a positioning block. The rotating sleeve is rotatably mounted on the top of the base. The bottom of the rotating sleeve is provided with a through hole, which is opened on the base. A positioning block that can move left and right about the side wall of the round rod is elastically mounted on one side wall of the rotating sleeve. The positioning block is fixedly connected to a connecting rod. The round rod is inserted into the rotating sleeve. A plurality of equally spaced positioning grooves are opened along the length direction on one side wall of the round rod. The positioning block is embedded in one of the positioning grooves.

[0011] The bottom end of the round rod is connected to an elastic telescopic rod in a stretched state. The bottom end of the elastic telescopic rod is fixedly connected to a rectangular strip, which is pressed against the bottom of the mounting panel. A stop block is fixedly installed on the top of the rotating sleeve.

[0012] Furthermore, a gripping head is fixedly installed at the top end of the round rod.

[0013] Furthermore, the positioning block is connected to the guide hole on the inner wall of one side of the rotating sleeve with a clearance fit. A second spring is provided in the guide hole.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Please see Figure 1-6 As shown, a skid-mounted vehicle-mounted oilless screw powder conveying air compressor includes: a base 1, a vehicle-mounted oilless screw powder conveying air compressor body, an installation component 12, and an installation panel 14.

[0036] The base 1 has a vehicle-mounted oil-free screw powder conveying air compressor body on its top; the base 1 has multiple mounting components 12 arranged in a rectangular array; the base 1 is detachably mounted on a mounting panel 14 via the multiple mounting components 12, such as... Figure 3 As shown, four mounting components 12 or other numbers of mounting components 12 can be used to achieve the installation between the base 1 and the mounting panel 14.

[0037] like Figure 1-2 As shown, the main body of the vehicle-mounted oilless screw powder conveying air compressor includes: a motor 2, an oil cooler 3, an oil-gas separator 4, a connecting pipe 5, an air outlet pipe 6, a conveying pipe 7, an air filter 8, a screw compressor 9, an air inlet pipe 10, a control cabinet 11, a gearbox 13, and an oil return pipe 17. The output shaft end of the motor 2 is fixedly connected to the input end of the gearbox 13, and the output end of the gearbox 13 is connected to the screw compressor 9. One end of the outer casing of the screw compressor 9 is fixedly connected to the air inlet pipe 10, and the air inlet pipe 10 is connected to the air filter 8. The other end of the outer casing of the screw compressor 9 is fixedly connected to the conveying pipe 7, and the conveying pipe 7 is connected to the oil-gas separator 4. The oil-gas separator 4 is equipped with an air outlet pipe 6, and the oil-gas separator 4 is connected to an oil return pipe 17. The oil cooler 3 is connected to an oil return pipe 17, which is connected to the bottom of the casing of the screw compressor 9. The control cabinet 11 is mounted on the base 1. The above describes the structure of the main body of the vehicle-mounted oilless screw powder conveying air compressor. It is driven by a motor 2 and driven by a pulley in the gearbox 13 to achieve speed change, which drives the screw in the screw compressor 9 to rotate. This drives the external airflow to enter one end of the screw compressor 9 after being filtered by the air filter 8, and exits from the other end of the screw compressor 9. It enters the oil-gas separator 4 through the conveying pipe 7 and the connecting pipe 5. The air is discharged through the air outlet pipe 6. The separated oil enters the oil cooler 3 for cooling and enters the screw compressor 9 through the oil return pipe 17 to achieve oil return.

[0038] like Figure 4 As shown, the mounting assembly 12 includes: a rotating sleeve 1203, a round rod 1202, and a positioning block 1208. The rotating sleeve 1203 is rotatably mounted on the top of the base 1. The bottom of the rotating sleeve 1203 is provided with a through hole 15, which is opened on the base 1. A positioning block 1208 that can move left and right about the side wall of the round rod 1202 is elastically mounted on one side wall of the rotating sleeve 1203. The positioning block 1208 is fixedly connected to a connecting rod 1209. The round rod 1202 is inserted into the rotating sleeve 1203. A plurality of equally spaced positioning grooves 1207 are opened along the length direction on one side wall of the round rod 1202. The positioning block 1208 is embedded in one of the positioning grooves 1207.

[0039] The bottom end of the round rod 1202 is connected to an elastic telescopic rod in a stretched state. The bottom end of the elastic telescopic rod is fixedly connected to a rectangular strip 1211, and the rectangular strip 1211 is pressed against the bottom of the mounting panel 14. A stop block 1215 is fixedly installed on the top of the rotating sleeve 1203. The above describes the component state of the mounting assembly 12 when the base 1 and the mounting panel 14 are installed.

[0040] The elastic telescopic rod is in a stretched state, providing elastic tension to the round rod 1202 and the rectangular bar 1211, so that the base 1 and the mounting panel 14 are clamped together, while providing pressure to the rotating sleeve 1203, making it difficult for the rotating sleeve 1203 to rotate, thus providing friction limit.

[0041] A gripping head 1201 is fixedly installed at the top of the round rod 1202, which facilitates the operation of the round rod 1202.

[0042] The positioning block 1208 is clearance-fitted with a guide hole 1212 on the inner wall of one side of the rotating sleeve 1203. A second spring 1214 is provided in the guide hole 1212. One end of the positioning block 1208 is fixedly connected to one end of the second spring 1214, and the other end of the second spring 1214 is fixedly connected to the wall of the guide hole 1212. The guide hole 1212 communicates with a guide hole 1213, which is located on the outer wall of the rotating sleeve 1203. The guide hole 1213 is clearance-fitted with a connecting rod 1209. The positioning block 1208 slides in the guide hole 1212 to achieve left and right movement. The second spring 1214 provides a reset function after sliding. The connecting rod 1209 facilitates pulling operations. The positioning block 1208 can be moved by pulling on one side of the rotating sleeve 1203.

[0043] The bottom of the positioning block 1208, which is away from the connecting rod 1209, is provided with an inclined surface. When the round rod 1202 moves upward, the bottom of the positioning block 1208 can be pushed through the positioning groove 1207, so that the positioning block 1208 can move left and right.

[0044] When the round rod 1202 rotates, the rotating sleeve can rotate together through the action of the positioning block 1208.

[0045] The bottom of the rotating sleeve 1203 is fixedly installed with a rotating ring seat 1210, which is connected to the rotating groove opened on the base 1 with clearance, so as to realize the rotating installation.

[0046] The elastic telescopic rod includes: a first spring 1204 and a square rod 1205; the square rod 1205 is clearance-fitted with a square hole 1206 opened in the middle of the length direction of the round rod 1202, the first spring 1204 is disposed inside the square hole 1206, the top end of the square rod 1205 is elastically connected to the bottom of the grip head 1201 through the first spring 1204, and the bottom end of the square rod 1205 is fixedly connected to the middle of the rectangular strip 1211; one end of the first spring 1204 is fixedly connected to the bottom of the grip head 1201, and the other end of the first spring 1204 is fixedly connected to the top end of the square rod 1205.

[0047] The mounting panel 14 has multiple rectangular slots 16 that match the rectangular strip 1211. The rectangular strip 1211 and the rectangular slots 16 have the same length and width and are aligned with each other. The rectangular strip 1211 can pass through the rectangular slots 16.

[0048] During installation, simply rotate the round rod 1202 to align the rectangular strip 1211 with the rectangular groove 16 on the mounting panel 14. Place the base 1 on the mounting panel 14, where the rectangular strip 1211 moves to the bottom of the mounting panel 14 through the rectangular groove 16. Then rotate the round rod 1202, causing the rectangular strip 1211 to rotate 90°. Pull the round rod 1202 upward. Because the rectangular strip 1211 is blocked by the mounting panel 14, the elastic telescopic rod is stretched, causing the round rod 1202 to move upward. During the movement, the positioning groove 1207 presses against the inclined surface at the bottom of the positioning block 1208, allowing the positioning block 1208 to move horizontally. After the movement, the second spring 1214 provides a reset for the positioning block 1208, allowing it to be reinserted into the moved positioning groove 1207 until the positioning block 1208 is embedded in the lowest positioning groove 1207 of the round rod 1202, completing the installation. At this time, the first spring 1204 is in a stretched state, providing a stretching force that clamps the base 1 and the mounting panel 14, completing the installation. The top of the positioning block 1208 is flat, which will obstruct the positioning groove 1207, preventing the round rod 1202 from automatically resetting. It can be locked after the round rod 1202 is pulled. After installation, as... Figure 4 As shown.

[0049] During disassembly, pulling the connecting rod 1209 separates the positioning block 1208 from the positioning groove 1207, compressing the second spring 1214 and resetting the first spring 1204, causing the round rod 1202 to descend until the gripping head 1201 contacts the stop block 1215. Releasing the connecting rod 1209 allows the positioning block 1208 to reset and insert into the positioning groove 1207 for repositioning. Then, the gripping head 1201 is rotated 90° to align the rectangular strip 1211 with the rectangular groove 16, completing the positioning contact. The base 1 is then lifted to complete disassembly. After disassembly, as shown... Figure 6 As shown.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
